Hello, welcome to Android Forums.
Could you give a bit more information please - I'm assuming you are referring to the 'blue dot' location shown on Google Maps or other navigation app.
Does the location move between two specific places or more than two and is one of them your actual location.
What 'mode' are you using in your 'location settings' when this happens?
I'm assuming that if you select 'device only' and get a GPS 'fix' it gives you a correct and steady location.
